The storage module 16 can be a flash memory, a read-only memory, a programmable read-only memory, an electrically rewritable read-only memory, an erasable programmable read-only memory, or an electrically erasable programmable read-only memory.

The control module 11, the communication module 13, the power module 14, the storage module 16, and the map analysis module 18 are disposed inside the casing 10. The first sensor module 17 is disposed inside or on an outer side of the casing 10. The moving module 15 is disposed on a bottom side of the casing 10.

Referring to FIG. 2 and FIG. 3, the moving module 15 includes a motor 151 and a moving unit 152. The motor 151 is connected to the moving unit 152. The motor 151 receives a driving signal to drive the moving unit 152.

The moving unit 152 includes a plurality of steering gears, a plurality of wheels, or a plurality of crawler belts, and the motor 151 is connected to the moving unit 152, such that the air purification device 1 can move in all directions.

In this embodiment, the first sensor module 17 includes a particulate matter sensor 171 (PM2.5 sensor) and an olfactory gas sensor 172. Both the particulate matter sensor 171 (PM2.5 sensor) and the olfactory gas sensor 172 of the first sensor module 17 are electrically connected to the control module 11. The first sensor module 17 can further include a temperature sensor, a humidity sensor, or an illuminance sensor. The air purification device 1 can periodically transmit a plurality of environmental parameters (i.e., brightness, temperature, and humidity) to the server 2, to continuously monitor the environment of the predetermined area. In addition, the server 2 can be connected to other intelligent electrical appliances, such as lighting devices, audio equipment, humidifiers, and air-conditioners, within the predetermined area. Furthermore, the server 2 can adjust another plurality of environmental parameters of the predetermined area according to the environmental parameters of the air purification device 1.

The second sensor module 19 includes at least one of an infrared sensor 191 or a laser ranging sensor 192.

The second sensor module can further include at least one of a gyroscope sensor, a geomagnetic sensor, an optical sensor, an infrared sensor, a laser ranging sensor, an olfactory gas sensor, a weight sensor, and an image capture sensor. In other embodiments, the gyroscope sensor and the geomagnetic sensor are used to confirm whether or not the casing 10 of the air purification device 1 is tilted when moving around.

The laser ranging sensor 192 or the infrared sensor 191 of the second sensor module 19 is disposed on the outer side of the casing 10. In this embodiment, the second sensor module 19 can include two laser ranging sensors 192 and two infrared sensors 191, which are respectively disposed on a top side and a bottom side of the casing 10. Although the map data (two-dimensional map) and the route are provided for guidance, since the air purification device 1 has a certain height, sensors are respectively disposed on the top side and the bottom side of the casing 10 to avoid obstacles with different heights that are portrayed in the map data.

Since the infrared sensor 191 or the laser ranging sensor 192 of the second sensor module 19 are used to measure the predetermined area in this embodiment, a size of the predetermined area is first recorded. Afterwards, the obstacles or the furnishings in the predetermined area can be measured. After the size of the predetermined area is recorded, coordinates of the predetermined area can be analyzed and established. The resolution of the coordinates can be determined by a minimum moving distance of the moving module 15. In this way, a map of the predetermined area can be used to determine the movement of the air purification device 1.

References are made to FIG. 4 and FIG. 5. FIG. 4 is a schematic view showing the air purification device moving according to a first route in one embodiment of the present disclosure. FIG. 5 is a schematic view showing the air purification device moving according to a second route in one embodiment of the present disclosure.

The control module 11 obtains a first route PATH1 according to the map data, and drives the moving module 15 to perform an air quality detection procedure of a plurality of locations L1 to L9 in the predetermined area through the first route PATH1 and the particulate matter sensor 171 of the first sensor module 17, so as to obtain a plurality of air quality parameters of the locations L1 to L9. The control module 11 uses the particulate matter sensor 171 to perform the air quality detection procedures at the locations L1 to L9 in the predetermined area to obtain the air quality parameters at the locations L1 to L9, respectively. The sequence of the first route PATH1 can be set by the user or determined by the air purification device 1 based on an analysis of the map data of the predetermined area. In addition, a plurality of sub-regions H1 to H8 of the predetermined area can be respectively arranged with one or more locations for air quality detection procedures to be performed. In this embodiment, the air purification device 1 sequentially moves from the location L1 to the locations L2 to L9 to perform the air quality detection procedures. In this embodiment, in addition to a detection of an amount of particulate matters, each of the air quality detection procedures also includes a detection of the environmental parameters, such as humidity and temperature. That is, in this embodiment, the air purification device 1 can further include a humidity regulator (not shown in the figures) to adjust the humidity of areas with a lower humidity or a higher humidity.

The air quality parameters of the locations L1 to L9 are mainly based on the amount of particulate matters detected by the particulate matter sensor 171. In this embodiment, the greater the amount of particulate matters, the lower the air quality parameters. The lower the amount of particulate matters, the higher the air quality parameters. The respective air quality parameters of the locations L1 to L9 are arranged in a sequence from low to high. That is, in this embodiment, the air quality parameters are arranged from low to high in a first sequence of the air quality parameters. For example, the first sequence of the respective air quality parameters of the locations L1 to L9 from low to high is: the location L8, the location L7, the location L6, the location L5, the location L4, the location L9, the location L3, the location L1, and the location L2.

Subsequently, referring to FIG. 5, the control module 11 generates a second route PATH2 according to the first sequence of the air quality parameters of the locations L1 to L9 (the air quality parameters are arranged from low to high). The second route PATH2 starts at the location L8, then moves sequentially to the location L7, the location L6, the location L5, the location L4, the location L9, the location L3, the location L1, and finally to the location L2.

That is to say, the control module 11 drives the moving module 15 according to the second route PATH2 to perform the air purification procedure at each of the locations L1 to L9 in the predetermined area. As mentioned above, the air purification device 1 starts at the location L8, then moves sequentially to the location L7, the location L6, the location L5, the location L4, the location L9, the location L3, the location L1, and finally to the location L2, thereby performing the air purification procedures at different locations.

In this embodiment, the first route PATH1 and the second route PATH2 can both be provided by the map analysis module 18. However, for more complex routes, e.g., routes with more than 10 locations that require the air purification procedures to be performed, the control module 11 will transmit the map data and the locations to the server 2. The server 2 can plan and calculate the route on the map data and data of the locations, and then transmit the calculated route back to the control module 11 of the air purification device 1. Therefore, the control module 11 can drive the air purification device 1 to move according to the calculated route provided by the server 2 and complete the air purification procedure.

In addition, when the first route PATH1 or the second route PATH2 is controlled by the control module 11 to drive the moving module 15, the air purification device 1 is moved to the locations in the predetermined area to perform the air quality detection procedures or the air purification procedures, so that the infrared sensor 191 or the laser ranging sensor 192 of the second sensor module 19 can continuously provide the control module 11 with a moving signal. The moving signal includes distances to the obstacles and changes of the distances. Furthermore, the air purification device 1 can also determine a current moving speed of the moving module 15, and an estimated time of arrival of each of the locations.

Furthermore, when the air purification device 1 performs the air quality detection procedure at each of the locations L1 to L9, the air purification device 1 simultaneously uses the olfactory gas sensor 172 to detect odors, such as a smell of smoke. The olfactory gas sensor 172 can also be set to detect special odors, such as smoke, outdoor exhaust, formaldehyde, alkanes and odors of other chemical gases.

When the olfactory gas sensor 172 detects an odor (a predetermined gas), the olfactory gas sensor 172 sends an odor signal to the control module 11, and the control module 11 turns on the deodorization module 12 according to the odor signal. That is, whether or not the deodorizing module 12 is turned on or not is determined according to whether or not the olfactory gas sensor 172 detects the predetermined gas. In this embodiment, the olfactory gas sensor 172 is provided on the outer side of the casing 10. The deodorization module 12 includes a fan 121 and a deodorization unit 122. The deodorization unit 122 can include deodorization agents, fragrances, essential oils, etc. When the olfactory gas sensor 172 detects a location with the odor, the deodorization module 12 of the air purification device 1 blows the deodorization agent in the deodorization unit 122 to the location with the odor by the fan 121. After a period of time, the control module 11 of the air purification device 1 can perform an odor detection again by the olfactory gas sensor 172. The air purification device 1 can repeatedly perform the odor detection and the deodorization until the odor is eliminated.

In addition, when the olfactory gas sensor 172 detects an odor, the air purification device 1 can transmit an odor information and a location information to the server 2 through the communication module 13. The server 2 can control an air-conditioner at the location with the odor according to the odor information and the location information, so as to have indoor air at the location with the odor rapidly replaced.

Reference is made to FIG. 6, which is a schematic view showing the air purification device detecting a crowd and approaching towards a location of the crowd in one embodiment of the present disclosure.

The air purification device 1 in this embodiment can detect heat of the human body via the infrared sensor 191. When people gather as a crowd U at a location, the air purification device 1 can move to the location of the crowd U to perform the air purification procedure according to a detection of the infrared sensor 191.

In this embodiment, the power module 14 is disposed in the casing 10 and is electrically connected to the control module 11. The power module 14 includes a battery unit 141 and a charging unit 142. The battery unit 141 provides a driving power to the control module 11, the deodorization module 12, the communication module 13, the moving module 15, the storage module 16, the first sensor module 17, the map analysis module 18, and the second sensor module 19. The charging unit 142 is electrically connected to the battery unit 141.

When the battery unit 141 has a power lower than a predetermined power value, the control module 11 provides a low power driving signal and a charging route to the moving module 15 according to the map data, such that the air purification device 1 can seek out a charging base according to the charging route and is charged.

The battery unit 141 is a lithium ion battery, a lithium manganese battery, a nickel hydrogen battery, or a lithium ion polymer battery. The charging unit 142 is a wired charging unit or a wireless charging unit. The charging base is a wired power base or a wireless power base. When the charging unit 142 is a wired charging unit, the charging unit 142 may be an alternating current to direct current (AC-DC) voltage converter or a DC-DC voltage converter. When the charging unit 141 is a wireless charging unit, the charging unit 141 includes a wireless charging coil. In addition, the charging unit 141 may include a wired charging unit and a wireless charging unit simultaneously, and adjust and switch the corresponding charging unit according to a detected type of the charging base.

In this embodiment, the air purification device 1 can be communicatively connected with a mobile device 9 or the server 2 through the communication module 13. That is to say, the user can directly send the coordinates of the target location to the air purification device 1 through the mobile device 9 and request the air purification device 1 to move to the target location. On the other hand, the user can also send the coordinates of the target location to the server 2 through the mobile device 9, and the server 2 sends the moving signal to the air purification device 1 to move the air purification device 1 to the target location. Moreover, the server 2 can also provide the map data to the air purification device 1. Furthermore, the server 2 can provide more complex map analysis functions. When the predetermined area is relatively complex and large, a function of route analysis can be performed by the server 2.

In this embodiment, the mobile device 9 can be a smart phone, a tablet computer, a desk computer, a notebook computer, or a wearable electronic device.

In this embodiment, the communication module 13 includes a wired communication unit (not shown in the figures) and a wireless communication unit (not shown in the figures). The wired communication unit (not shown in the figures) can work in cooperation with the power module 14, and be communicatively connected with the power module 14 through wires. The wired communication unit (not shown in the figures) can also be arranged independently to be communicatively connected with the server 2, and receive the control signal of the server 2 or data in a database.

The wireless communication unit (not shown in the figures) can be a WI-FI® communication unit, a BLUETOOTH communication unit, a ZIGBEE® communication unit, a LoRa communication unit, a Sigfox communication unit, or an NB-IoT communication unit.

Reference is made to FIG. 7, which is a schematic view showing a plurality of particulate matter sensors arranged in a predetermined area in one embodiment of the present disclosure.

In the sub-regions H1 to H8 of the predetermined area, the particulate matter sensors PM1 to PM6 can also be arranged to be connected to the server 2 through wireless communication. The particulate matter sensors PM1 to PM6 in the sub-regions H1 to H8 can periodically transmit the respective air quality parameters of the sub-regions H1 to H8 to the server 2. The server 2 can select one or more of the sub-regions H1 to H8, plan a route for the one or more selected sub-regions, and provide the route for the one or more selected sub-regions to the air purification device 1 according to the respective air quality parameters of the one or more selected sub-regions. The air purification device 1 then moves to each of the one or more selected sub-regions to perform the air purification procedure according to the one or more selected sub-regions provided by the server 2. In addition, the server 2 can also directly provide the respective air quality parameters of the sub-regions H1 to H8 to the air purification device 1, such that the control module 11 and the map analysis module 18 of the air purification device 1 are able to plan a route autonomously.
